    These data files represent simulations of hydrated cation vacancies in the mantle mineral forsterite (Mg2SiO4) undertaken using the CASTEP atomic scale simulation code (http://www.castep.org/). Results from these simulations allow the structure relative stability of different defect configurations to be compared. Three types of cation vacancies are considered (M1, M2 and Si) each decorated by hydrogen in order to charge balance the system. For M1 and M2 this results in multiple configurations (with hydrogen bonded to different oxygen atoms around the vacant site). For Si there is only one configuration as all four oxygen atoms are bonded to hydrogen for the charge neutral defect. For each configuration input files detail the initial atomic structure of the defect along with simulation parameters. Output files record the progress of the simulation, the final atomic structure, the energy of this structure, and various predicted properties of the structure. Only ASCII output data is included as binary data created by CASTEP is not intended to be portable, and can easily be recreated using the ASCII files.

    High frequency (100 Hz) data from two horizontal induction coils measuring the Earth's magnetic field at the Eskdalemuir Observatory in the United Kingdom. The data covers the period from January 2018 to December 2018. Also included are examples of Matlab code and the frequency calibration files to convert to the raw data to SI units. Thumbnail spectrograms and metadata are also supplied.

    This dataset contains tabulated production, consumption and trade data on minerals in the UK together with authoritative commentary on current developments in the minerals industry. Data are supplied from official sources, companies and trade associations. Where data cannot be acquired, estimates are given. In addition to UK (country) data, statistics are also given at planning region level and, for certain minerals, at county level. Units of measurements are tonnes, kilograms or carats, according to commodity. Value is also provided for imports and exports. The information will be of value to all those interested in Britain's minerals. The data captured by BGS spans from 1973 onwards and is updated annually.

    A digital geochronological index to act as a domain constraint for geochronology columns in corporate data tables. It decodes geochronology codes, models pseudo parent-child relationships between intervals (for example, find the epochs within a given period), allows range searches (for example, find the epochs between lower limiting and upper limiting epochs) and provides radiometric ages with ranges of uncertainty. Follows the recommendations of the BGS Stratigraphy Committee. Phanerozoic after Gradstein and Ogg (1996), with the Ordovician scheme of Fortey et al. (1995); Proterozoic after Cowie and Bassett (1989); Archaean after an unpublished decision of the Precambrian Subcommission of the IUGS. Covers the whole of geological time. Geochronological resolution usually to age level. Lower resolution in the Archaean, Proterozoic, Cambrian. Greater resolution in the Caradoc Epoch.

    The NIGL (NERC Isotope Geosciences Laboratories) laboratory records comprise paper output from mass spectrometers, which is retained for 5 years from the date of analysis, and mass spectrometer loading sheets, which are retained indefinitely. NIGL is a comprehensive stable and radiogenic isotope laboratory facility that undertakes environmental, life, archaeological and earth science research, and educates and trains PhD students, in a collaborative research environment.

    Scanned collection of seismological journals and offprints. The original collection was compiled by John Wartnaby. John Wartnaby was a curator at the Science Museum, London, and wrote a historical survey of seismology and scientific instruments. His accumulated papers consist chiefly of offprints and articles, and many older British Association seismological reports. The collection is part of the National Seismological Archive.
